CHRISTIAN H. BROCKMANN, OF UNIN CENTER, WISCONSIN.

, DRAFT EQUALIZER.

Application filed February 24, 1920. `Serial No. 360,886.

To all 11i/mm 'it may conce/M1,

MANN, a. citizeniot' the United States, residing at Union Center, in thecounty of Juneau and State ot Wisconsin, have .invented certain new anduseiful improvements in Draft Equalizers, ot which the following is aspecilication.

This in vcntion relates to improvemei'its in drait equalizers and haslor its object to con struct an equalizer that tends to equalize theside draft.

in important object of the invention is to provide a reversibleequalizer.

A still further object of the invention is to provide an equalizerwhich. may be secured to any farm vehicle or draft implement either withor without a tongue and which may be held by an ordinary piu or clevis.

With the above and such other objects in view as may hereinafter appear,l have in` `vented the device illustrated in the accompanying' drawingsin which- Figure 1 is a top plan ot an equalizer when used for twohorses. i

Figure 2 is a similar view with a plate removed and an extension for athird horse attached. y

Figure 3 is a section on line 3-3 Figure 1.

Figure l is a section on the linee-ll of Figure 2.

Like reference characters indicate like parte throughout the followingspecification and iu the several views in the drawings in which 1 is anequalizer lor two or three horses, the ratio indicated as one to two,how` ever`r it may be built in a ratio of one to three or one to tour,tour or tive horses may be used abreast required, one horse in theturrow and the others on the land when used in connection with gangplows, ete. The device consists oif a housing comprising sup portingplates and on equalizer bar l e@ centrically pivoted 5 between saidplates., and 7 pivoted to the ends ot draft bars 6 i 5 said bar It,`fulcr m l'earings S and 9 for said j hars and Tand an extension bar 10tor the bar 7. i

An oliset hearing 11 is provided on plate 2 which tubular andalignswvith a similar oitl'set tubular member 12 on plate 3 throughwhich a drait pin or clevis may be secured to attach the device to thedrawnimplement. As clearly seen in Figure 5, the bearing boss 12 isprovided with a reduced tubular extension which projects through theopenthe bar e are slotted to receive the ends 19 i and 2O of the draft`barsl 6 and 7 rivets `21 and 22 passing through said ends 17 and 18project through elongated slots 23 and 24 inthe ends 17 and 18, wherebysaid bars 6 and '7 are pivoted to the bar 4 and play between saidmembers is provided so as to permit sutiicient flexibility of theequalizer. It will be noted that a shorter tulcrum end 19 is provided onbar 6 than the iulcrum end 2() of bar 7 the latter being the end towhich the larger number of horses are `hitched when being used for ymorethan two draft animals, in which case the extension bar 10 is attachedto bar 7 and fixedlysecured thereto by means of the bolts 25 and 26 andthe flanges 27 and 28 of said bar 1() which straddle the end of bar 7The plates 2 and 3 are secured together by a series of bolts 2S and 29which project through collars 30 which form spacers between the plates 2and 3.

Une particular advantage of the above described device is that it may bereversed so that the odd horse may work on either side of the vehicle orimplement.` Another special advantage is that merely by removing orreplacing the bolt 16 the device may` be converted into' either anordinary double tree or an equalizer tor three or more horses. l Havingnew described my invention, that which 1 claim as new and desire toprocure by Letters Patent is:

1f draft equalizer com rising plates, each having an opening, a tubularboss formed on each plate surrounding the opening therein, an equalizerbar having an opening therein, and one of said bosses having a reduced.tubular extension adapted to project through the opening in theequalizer bar and abut with the coacting bossfor properly spacing thebosses from the bar.

2. A draft equalizer comprising a pair of plates,re`tained in spacedrelation to each a pair of other, Vdraft bars iliulciulned between thepin insel'tible into the aligning apertures ol plates :purl at theirends, an equalizer bar the pair of plates, and the equalizer bar fordisposed between the draft bars and pivoted locking' the latter againstmovement.

eccentric-Cilly between the plates, said pair of ln testimony whereof Iax my signa- 5 plates having aligning)` apertures disposed ture in thepresence of two witnesses. 15
